What this website publishes for an AI agent to read, use and buy from, on a scale of six levels.
- 0
- 1
- 2
- 3
- 4
- 5
Level 0: Not yet agent-ready. Agents struggle to find basic information about the site.
- 2 of robots.txt, Sitemap, Link headers
Some checks could not run. With them, up to level 1 would be possible.
The website turns away requests that do not come from a browser. AI agents that say what they are meet the same refusal.
